[j-nsp] VMX to VMX traffic on ESXi

[Raphael Mazelier]

I have got some strange problem with vmx on vmware.
First double check if all our vswitch are in promiscuous mode.
Check also if you use vxnet or e1000 type of interface, I've got erratic 
problems with vxnet, and gave up with it.
Check the mac address mapping, and finaly check if you have proper 
license installed ;) (I've spend one hour to find why one of my test vmx 
does not anymore, before I found that the license have expired...)
